Abstract
La présente invention concerne une composition élastomère thermodurcissable à base de polycyanurate modifié à tenue thermique améliorée susceptible d'être obtenue par un procédé de polymérisation en présence d'un catalyseur (D) d'u n mélange comprenant au moins: (A) un cyanate; (B) un copolymère bloc constitu é par: a) au moins un bloc (B1) central non miscible avec le cyanate et suffisamment long pour donner à la composition un caractère élastomère; et b ) au moins deux blocs terminaux (B2) situés de chaque côté du bloc central et comportant des groupes réactifs avec le cyanate, chacun des blocs (B2) étant suffisamment longs pour être miscibles avec le cyanate; et (C) une charge minérale réactive avec le cyanate, dans des proportions telles que le rappor t r soit au moins égal à 5, mais reste inférieur à une valeur limite pour évit er l'inversion de phase ledit procédé comprenant les étapes de: I) mélange de (A), (B), (C) et (D) jusqu'à l'obtention d'un mélange homogène à une température supérieure à la température de fusion de (A) et de (B) mais inférieure à environ 130 ~C; II) polymérisation du mélange à une température comprise entre environ 130 et environ 170 ~C; III) post-cuisson du mélange polymérisé à une température supérieure ou égale à environ 200 ~C pour compléter la réaction; les valeurs de .DELTA..sigma.rupt et de .DELTA..epsilon.rupt de la composition ainsi obtenue étant inférieures ou égales à +-30 %. La présente invention concerne également le procédé de préparation de cette composition et son utilisation.
